The mailing list for listmasters using Sympa

[Richard Caldwell <address@concealed>]

Does anyone have any suggestions for rate controlling outgoing messages
from our listserver?

Many of our students forward their student email address to a home ISP.
Mass mailings to students create many messages to large ISPs as these
messages are forwarded.  As a result we have occasionally been rate
controlled or black listed by ISPs.

Right now we're using Postfix as a MTA and I haven't found anything that
seems useful there.  Most the rate control information I've found is
directed toward controlling incoming SPAM.

Thanks,
Richard
